Consumption of steel grinding media in mills A review it was found that the consumption of media in ball mills during grinding operation can be up to 50% of grinding operating costCalculate and Select Ball Mill Ball Size for Optimum Grinding,In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and
In the tumbling mills (autogenous, semi-autogenous, rod and ball) wear is generally expressed in terms of steel consumption per ton of ore ground or per kWh consumed by the mill. When comparing the wear rate of different ores in different types of mills, unit weight/kWh is considered a better measure.(PDF) A comparison of wear rates of ball mill grinding media,In ball milling, materials consumption by wear represents a very high production cost, and must be minimized by the proper selection of materials, especially those for balls.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous millball consumption in grinding mills NAMARI Heavy Machinery,ball consumption in grinding mills. Steel consumption of balls is spread out over an even greater range Some indication as to media consumption can be obtained from power consumed in grinding For example balls or rods will generally wear at a rate of about 1 for each 6 or 7 kilowatt hours consumed per ton of ore
